Description
Summary:The construction industry is in search of cleaner and greener alternatives for materials in concrete. The main objective of this study was to determine the properties of concrete using recycled ceramic waste aggregates (CWA). In this study, natural fine and coarse aggregates were partially substituted as ceramic waste aggregate in the range of 25%, 50% and 75%. Fifty-four cubes and twenty-one cylinders were prepared and tested to obtain the physical and mechanical properties of concrete. The compressive strength of concrete specimens containing 50% recycled ceramic fine aggregates (CFA) and 75% recycled ceramic coarse aggregates (CCA) is greater than the conventional concrete. However, the modulus of elasticity decreased with increased recycled aggregate content. The aggregates replacement decreases the concrete density but satisfying the desired compressive strength of concrete. The results made it possible to adopt ceramic tile waste as recycled aggregate materials to promote sustainable development in the production of concrete.
